Putty SSH: CTRL+Cursor keys don't work skip to previous/next word

Add these two lines to your ~/.inputrc file on the destination machine:

"\eOD": backward-word
"\eOC": forward-word

To make sure that they are the correct sequences, at a Bash prompt, type Ctrl-V Ctrl-LeftArrow and Ctrl-V Ctrl-RightArrow, you should see:

^[OD^[OC

When you start a new session, the keys will be available or you can press Ctrl-xCtrl-r to re-read the ~/.inputrc file for the current session.

For the Linux console:

"\e[1~": beginning-of-line
"\e[4~": end-of-line
"\e[5~": beginning-of-history
"\e[6~": end-of-history
"\e[3~": delete-char
"\e[2~": quoted-insert
